This study was carried out to investigate the accumulation of Fe, Mn, Cd, Pb, and Ni in Terapon puta from Karachi Fish Harbor, Pakistan. There were no significant differences in the concentration of the metals except Mn in T. puta, which is obtained from the different seasons. The highest metal concentration is Fe followed by Mn. Cd, Pb, and Ni were measured relatively lower concentrations. The mean (± SD) Fe, Mn, Cd, Ni, and Pb levels in the muscles tissues of T. puta were 25.5±13.71, 6.07±3.58, 0.47±0.29, 0.46±0.27, and 0.43±0.25 mg/kg dry wt., respectively, whereas the mean (± SD) Fe, Mn, Cd, Ni, and Pb levels in the liver tissues of T. puta were 562±105, 18.62±11.86, 1.06±0.47, 1.20±0.53, and 1.01±0.50 mg/kg dry wt., respectively. Cd and Pb levels exceeded the Commission Regulation of European Union maximum limit of 0.05 mg/kg and 0.30 mg/kg, respectively. However, the results of Estimated Weekly Intake and Estimated Daily Intake indicate that the heavy metal levels in the samples are generally within respective recommended guidelines. Thus, it would appear from this study that the heavy metal levels in T. puta from Karachi coasts are low enough not to present a health hazard if the fish are consumed, although due attention should be paid to the maximum acceptable daily intake per kilogram body weight
